Hello internals
The upgrading guide lists that the option --with-libxml-dir is removed in PHP 7.4 (https://github.com/php/php-src/blob/PHP-7.4/UPGRADING#L763 https://github.com/php/php-src/blob/PHP-7.4/UPGRADING#L763). Unfortunately on MacOS, header files are not stored in the usual locations, which means that compiling PHP fails with the following error: fatal error: 'libxml/parser.h' file not found
With the removal of --with-libxml-dir, I wonder what the right way is to tell PHP where the header files are located.
As a sidenote: some might suggest using the built-in MacOS tool to install the header files in /usr/include (https://silvae86.github.io/sysadmin/mac/osx/mojave/beta/libxml2/2018/07/05/fixing-missing-headers-for-homebrew-in-mac-osx-mojave/ https://silvae86.github.io/sysadmin/mac/osx/mojave/beta/libxml2/2018/07/05/fixing-missing-headers-for-homebrew-in-mac-osx-mojave/), though this tool doesn't seem to work anymore in recent MacOS versions.
Kind regards
Brent
